Abstract
The method relates to an optimizing method for determining the optimum shape of plates such as sheets of sheet metal, panes of glass, or other thin objects designed in particular to retract completely in order to leave a clear opening. To simplify the use of shaped plates that have already been predesigned, they are modified such that their shapes coincide substantially with a "screwable" surface chosen from the wide variety of existing surfaces that meet screwability criteria and can hence move in the space without changing position, except for their edges. Implementation of the method allows the various constraints that may exist in the design of such plates to be met.
Claims5
Optimization method for determining an optimum shape to be conferred on a thin movable plate designed to be moved adjacent at least one curved wall or in a tight space delimited by two curved walls opposite each other, comprising predefining an initial shape of the plate as a function of imposed constraints and optimizing the initial shape to give the plate an optimum shape comprising a substantially threaded shape with a finite pitch and requiring it to meet a screwability criterion.
